General Properties Concerning Laser Coolingeed of atoms can be reduced by a considerable amount. Since the spread of velocities of a sample of atoms is directly related to its temperature, the field has been dubbed laser cooling, and this name has persisted throughout the years. Laser cooling has much in common with the field of optics. In l

Deceleration of an Atomic Beams to influence the motion of neutral atoms has been a subject of interest for some years, and several review articles and books on the subject are listed in Appendix B. The force caused by radiation, particularly by light at or near the resonance frequencies of atomic transitions, originates from th

Evaporative Coolingficiently low temperature and high density, a gas of atoms undergoes a phase transition that is now called Bose-Einstein condensation (BEC—see Chapter 17). This phase transition is predicted to occur at a phase space density ., where . is the density of the gas and .is the deBroglie wavelength of th
